Description

DIBBLB. Syringe.
Patented April 8,1879.

IMPROVEMENT IN SYRINGES.
Specification forming part of Letters Patent No. 213,978, dated April H, 1879 application filed .Novmber 13, 1876` To all 'whom 'it may concern.- y
Beit known that I, JoHN L. DIBBLE, of the city ot' Brooklyn, county of Kings, State of New York, have invented a new and useful Improvement in Syringes, which improvement is fully set forth in the following specification,
reference being had to the accompanying drawings.
. provided 'withV a 'partially-nclosed urethral syringe, so arranged that it may be repeatedly charged from the contents of the surrounding flask andl discharged will withv out separating the parts.
The following is what I ,onsiaer the best method of carrying out the invention.
Figure 1 is a longitudinal section of the apparatus in the pla-ne of its greatest diameter.
Fig. 4 is a cross section on the lineS S. Figs. 2 and 3 represent modifications inI the details of construction.
Similar letters of reference represent like parts in all the figures.
A is a ask, of any desired outline, but preferaby of a flattened oval form, as represented,
constructed of vulcanized india-rubber, guttapercha, or other suitable material. In ,the center of this ask, tightly'attached or tted into the bottom, and extending nearly the whole length of the interior of the flask, is the tube B, which forms a barrel for the syringe. Into this barrel is the piston b, connected with the rod or handle bl in the manner usual in the lconstruction of syringes.
The stopper C is so proportioned and constructed that it bea-rs tightly against both the end of the barrel B and the neck or mouth of the ask A. A lt is centrally pierced for a discharge-tube, C4, and is provided with a valve, Cl; and a vent, C, Vand performs the triple function of a cork or stopper for the-lask,
and, in combination with the tube B, a discharge-pipe and valve-case for the'syringe.
The nipple or point where the dischargepipe terminates is protected by the cap C, preventing its stoppage by dust or other matter from the pocket, and also covers the vent C2 when the instrument is not in' use.
Attached to the piston b is a projection, L2, of similar outline to the interior of the 'discharge-pipe.
The mode of operation will be readily understood. The flask having been filled in the manner of an ordinary vial, the operator removes the cap C3, holds the flask with the discharge-pipe downward, covering the dischargeorifice with the lin ger ofone hand, and draws up the handle or syrnge-rodvwith the other. The Huid enters through lthe valve Cand fills the syringe-barrel, while air Yis admitted through the vent C2 to supply its place. On forcing in the piston-rod the fluid is discharged through the discharge-pipe. The projection ou the pis ton enters and fills the discharge-pipe, driving out the iiuid and preventing drip. The operation may be repeated as long as sufticient fluid remains in the flask to ll the syringe-barrel. t
Many modifications may be made without departing from theprinciple ofthe inventionas, for instance, the barrel B ma be made solid with case A, or may be made eparately, and screwed or otherwise attached tothe case. The valve Cl may be a ball-valve, as in Fig. 1, or a flap-valve, as in Fig. 3, or of any other suitable fo'rm.
The cap C3 may be dispensed with, as also may the vent C2, in which case it will be necessary to-occasionally partiallyppen the stopper C to admit air to the case after using the apparatus; but in my view they are both desirable devices, and 'add to the perfection of the whole.
I am aware that patents have been issued to John Stull, 1856, and to G. Conover, 1870, for improvementsjn syringes, aiming to remedy some of the diicnlties referred to; but I considerVl my device better litted to accomplish thepurposes for which it is designed.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. A combined 'syringe and medicamentask constructed and arranged with the central barrel or tube, B, extending from the bottom of the ask to a point near its orice or neck, and forming, in connection with the stopper C and piston b, a syringe susceptible of being charged from the contents of the sur rounding flask and discharged at will by the` motion of the piston b, substantially as described and set forth. i
2. In combination with the case A and the barrel B, the stopper C, provided with discharge-tube C4, substantially as described.
3. In combination with the stopper C, and in connection with the interior of the case A and of the barrel B, the valve C', substantially as described.
4. In combination with the stopper C, and
in connection with the interior and exterior of the case A, the vent 0*,substantially as del JonN L. DIBBLE.
